The counterpoint to the controversy between Christ and Satan would be no controversy. The Bible clearly presents two sides or camps. One group of people are variously presented as God's possession and the second as opposed to God and God's authority. God's position in this war is clearly for good and against evil. Whether Christ and Satan are viewed as persons or personifications of these two ideals, the existence of the conflict must be acknowledged.
The logical next question is the importance and significance of the conflict as it relates to the individual person. The massive amount of writing in the Bible that is devoted to this topic reflects its value and importance as a guide for life. The Bible is a book that deserves study and application.
